Blankets Creek Singlespeeders

Just curious, what are you running for gears? I'm running a 32x18 (on a 29er) set up but am meeting lots of people who are running 32x19/32x20. I'm definitely not as strong as I usually am this season and am thinking about slapping a 19 on there. I can climb everything but at times I feel like I'm pedaling squares...
